Serial No. 277,754.

To all whom it may concern.'

Be it known that I, SIMON REINSBERG, a citizen of the United States, residing in Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Machines for Making Buttons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this si'iecification.

My invention relates to a machine for use in manufacturing pearl or other buttons and including therein means for milling the button blanks and drilling the eye-holes therein.

Figure I is a front elevation of my machine. Fig. II is a side elevation of the machine. ""g. III is a top or plan view of the machine. Fig. IV is a horizontal section taken on line IV IV, Fig. I with the parts beneath said line shown in plan view. I V is a horizontal section taken on line VAV, Fig. I with the parts beneath said line shown in plan view. V I is a horizontal section taken on line V Iw-VI, I, with the parts benea fh said Iine shown in plan view. Fig. VII is an enlarged plan vieur of a chuck table of the machine, the cam track adjacent to said table and one of the cutters, and also showing in cross section the stems of the drill chucks. F VIII is a vertical cross scction taken on line VIII-VIII, Fig. VII. Fig. IX is view partly in elevation and partly in vertical section of one of the chucks, the mechanism by which it is controlled and means for removing the :finished button from the chuck. Fig. X is an elevation of a modification of the means for milling the button blanks. Fig. XI is a top or plan view of the eXtra milling attachment shown in Fig. X.

l designates the main frame of my machine and 2 is an immovable column surmounting said frame and around which various parts of the mechanism of my machine operate. This column also serves as a support for other members of the machine.

3 designates a head frame that is clamped to the column 2 near its upper end and I is a hanger arm, see Fig. I, secured to and depending from the head frame 3. In this hanger arm is journaled a shaft 5 that is adapted to carry a milling wheel 6, the said shaft being provided with a pulley 7 to which power may be applied for the purpose of iinparting rotation to the shaft.

from the head frame 3. In this last named .hanger arm are iournaled the shafts 9 of drill chucks 1.0, each of which is designed to hold a drill a utilized in boring the eye-holes in the button blanks.

11 are spring stripper lingers suitably supported by the hanger arm 8 and straddling the drills for the purpose of stripping the button blanks therefrom after the drill has passed through them and is being withdrawn in the manner to be hereinafter described.

The shafts 9 of the drill chucks are equipped with pulleys l2 to which belts may be applied for the purpose of rotating the drill chucks.

13 designates a hanger arm secured to and depending from the head frame 3, see Fig. II. In this hanger arm is journaled the shaft 14 that is designed to carry a suitable reaming tool by which the button blanks may be conoaved. The shaft I4 is equipped with a pulley 15 adapted to receive a power belt.

16 designates a main drive shaft that is journaled in a standard 17, see Fig. II, and from which power is conveyed to the shafts of the milling, drilling and reaming tools previously mentioned.

I8 designates a chuck table rotatably fitted to the column 2 so as to revolve therearound. This chuck table is provided with a series of apertures 19 extending vertically therethrough and arranged in a circular course.

2() designates a turn table located beneath the chuck table 18 and loosely surrounding the column 2 so that said turn table and chuck table may revolve around said column with uniformity. The turn table has a hub 2i that extends above the main plane of the table and serves as a rest for the chuck table and also extends beneath the main plane of the table to provide for the application of means by which the chuck and turn tables are rotated, and also for the vertical reciprocation of the turn table by means to be hereinafter described. In the turn table 2O and in vertical alinement with the apertures 19 in the chuck table are apertures 22, see Fig. VIII.

23 designates a series of split chucks by which the button blanks l? are designed to be held. The chucks 23 may be of any desirable number according to the number S is a hanger arm secured to and depending l of tools that are to be used in operating upon vlilo the button blanks and so that two chucks will be susceptible of being brought to positions away from the tools at times and be opened to permit of the introduction of a button blank and the removal of a finished button on which the tools have operated. The shanks of the chucks are of less diameter than the apertures 19 in the chuck table and are centrally located in said apertures while the lower ends of the Shanks are seated in the apertures 22 in the turn table 2O to be carried thereby, the said shanks being preferably held in the last named apertures by nuts 24 a plied to their lower ends. Each of the chucks is provided with a recessed seat 25 in which the button blank is held and the shank of each chuck is provid ed with a longi tudinal bore.

26 are ejector rods located in the longitudinal bores of the chuck shanks and adapted to reciprocate therein for the purpose of lifting the buttons from the seats in the chucks after they have been finished. These ejector rods are actuated in a manner to be subsequently explained.

27 designates sleeves fitted in the apertures 19 in the chuck table and surrounding the shanks of the chucks 23. The sleeves are preferably conically formed interiorly, both at their upper and lower ends to provide both for proper bearing for the upper ends of the sleeves against the tapering heads of the chucks and lateral play of the sleeves. At the lower end of each sleeve is an annular iiange 28.

29 are lift springs that surround the chuck shanks and which rest upon the turn table 20 and bear against the lower ends of the sleeves 27. These springs serve to normally hold the sleeves in elevated positions so that they will engage the heads of the chucks to hold them in closed condition.

30 designates retracting yokes surrounding the sleeves 27 and having internal flanges 3l that are adapted to impinge against the annular flanges 28 of said sleeves. At the inner ends of the retracting yokes are pivot studs 32 that rest in the recesses 18 in thev perimeter of the hub of the chuck table 18. At the outer ends of the retracting yokes are rollers 33 adapted to be engaged by a member to be hereinafter mentioned and through the medium of which said yokes are tilted in a downward direction to retract the sleeves 27 and permit the chucks to open.

34 designates a lifting table loosely surrounding the hub 21 of the turn table 20 so as to be unaffected by rotation of said table. This lifting table is susceptible of vertical movement and it is directed in such movement by guide posts 35 surmounting the main frame of the machine, see Figs. I, H, IV and V. The posts 35 also serve to prevent rotation of said lifting table.

36 designates a pair of upright arms car ried by the lifting table 34. To the upper ends of these is attached a cam track 37 which is located adjacent to the perimeter of the chuck table 18 and is in the path of travel of the rollers 33 carried by the reti-acting yokes 30. During the rotation of the turn table 20 and chuck table 18 of the machine the rollers 33 pass beneath the cam track 37 when the chucks that are not passing beneath the tools of the machine are brought into positions to be opened and held in open position for the extraction of the finished buttons and the introduction of blanks to be operated upon. As each chuck containing a finished button is moved into proximity with one end of the cam t-rack the roller 33 of the retracting yoke corresponding to such chuck passes beneath the cam track, thereby causing the yoke to be tilted downwardly with a result of retracting the corresponding sleeve 27 and permitting the chuck to open for the extraction of the button. This chuck is then advanced and the next adjacent retracting yoke roller passes beneath the cam track to cause depression of the retracting yoke by which it is carried so that the button may be in turn extracted therefrom when the chuck opens. The chuck first opened at this time remains in open condition, due to the corresponding spreader yoke being still depressed by the cam track, and said chuck is in condition for the introduction of the button blank to be subsequently operated upon by the tools 'of the machine after the chuck has been closed when the turn table and chuck table are rotated another step to separate the first named retracting yoke from the cam track.

38 designates a finger wheel th at is carried by the hub ofthe turn table 20 and which is adapted to be actuated to impart an intermittent or step by step rotation to the turn table and chuck table of the machine.

39 designates a vertical driven shaft that is journaled in the lifting table 34 and has its lower end stepped into the main frame of the machine.

40 is a trip arm fixed to the shaft 39. This trip arm is provided with a roller 41 that is adapted to be carried into engagement with the fingers of the wheel 38 to impart intermittent rotation thereto and rotate the turn table and chuck table upon each complete rotation of the driven shaft 39. The shaft 39 has xed thereto a worm wheel 42, see Figs. l, H and Vl.

43 is a horizontal shaft with a pulley 44 to llO which power is communicated from the main 49, see Fig. l, that has slot and screw connection'with the bracket at 50 and is provided with an opening 5l adapted to register fith the opening` in the bracket. his adjustnient plate is held in adjusted position by a set screw 52 passing through the bracket at its lower end and bearingI against the lewe' end of the adjustnient plate.

53 designates a lifting yoke that surrounds the eoluinn 2 adjacent to its lower end. and is provided with an arin 54 which rests in the opening 4S of the bracket t7 and in the openinaI 51 of the adjustment plate 4Q, tlie said arni being adapted to be adjusted vertically by said adjustment plate. The lifting yoke is provided at its end opposite that bearing the arni 54 with a stein 55 that carries a roller 5G which riides upon the cani 46 carried by the driven shaft 3Q and through `the niediuiii of which said yoke is ii'ioved vertically. Vfithin the lifting yoke is a collar 57 that is loosely iitted to the colunin 2 to reciprocate vertically thereon beneath. the hub i`i ot the turn table 2O in order that when said collar is reciprocated it will iinpart vertical inovenient to the turn table and the parts carried by it. rlhe lifting yoke 53 is connected to the collar 57 by screws or pins 58 passing through the sides et the yoke and seated in said collar. It will be seen that when the driven shaft 39 is rotated the cani 46 will travel beneath the lifting yoke roller 56 and by raising' said yoke iinpart the desired vertical motion to the collar 57.

59 designates a cani Ylined to the driven .hatt 3Q adjacent to its upper end.

6U is a locking' bolt that is reciprocaliy positioned iii a `guide block (il. supported ""y an extension ariii Bel projetingr troni the liftingl table Bel. This lockingy boit is adapted to enter eit.-.er ot' a series ol notches Ziff in the tui'ii table 2G toi' the purpose of holding said turn table troni rotation when it is brought to the proper position tor one or more ot the button 'linisl'iing tools to operate upon a button blank carried by the chuck l() beneath the tool. The locking bolt is surrounded by an expansion. spring 62 that tends to force the bolt inwardly toward the turn table to enter oiie'of trie notches therein.

63 is a retracting l'ell crank lever pivoted at 64. to the lifting table extension aini. One arin et this lever is 'fitted to the locking holt and the other arni is provided with a roller 65 that is adaptedA to be engaged. by the cani 59, whereby uien the rotation. et the driven shaft 39 tiie cani 59 carried thereby will strike against said roller and act to rock the retractingl lever tor tie purpose of withdrawing the locking bolt troni the notch. in the turn table in which it was previously seated. The turn table is tl hereby treed to partake oi' its next intermittent iiieveiiient which is continued until the next adjacent notch in the turn table is brought into a position to receive ti'ie locking' 1volt.

84a, see ligs. l, il and IX, designates a cani surinouiiting the liltinp` table 34 in a position iiuiiiediateljT lencatli that to which .ach c-.iuck 223 of e .machine is brought at tire time t; chuck is to be opened as previously des ined, and the Viiiiislied button is to be discharged therefrom. r'"

iuis cani is adapted to lie ei'igap'ed by the ejector rods 26 passing longitudinally through the Shanks of the chucks and as the ejector rod in the chuck iroin which the linished button is to lie discharged is liiouglit to said Cain, it rides tbereoiito and is nioved vertically to litt the button trein the open chuck as seen in l ig. iX. ifi/*lien the buttons are released troni the chucks they inay lie conveyed liroin the inaclrine by any suitalile ineans such as a suction. pipe 66 shown in tig. li.

in its. X uid. Xl'. l have sown iiioditication in which the head traine 2% et the niaclaine carries in addition to the hanger ariu 4 and the iuiiling wheel 6 and its shaft, a second hanger ai'ni 4 in whic. is journaled a shaft 5. This slia'lit is equipped with a leveled pinion 5 that incsies with a leveled pinion 5b iixed to a sbatt 5C extending` at rig/wirt angles to the shaft 5. i shaft 5" is ad aptcd to have applied to it a milling' witt 6/ which is positioned at right angles to the milling wi eel 6 and which is adapted. to

operate upon the button blanks to produce a cross-cut groove therein extending at rip, angles to tl grooves produced by the .ifiiilling wheel 6. The buttons being produced, inay thereby be inade with crossing` grooves tor the seating ot threads therein in the usual in aniier.

While :l have shown only two drills to produce in the button blanks a pair ot eyeholes, it is t ious that the nuniber of drills inay be increased or doubled in order that the eye-holes inade in the buttons inay he tour in number instead of two in nuinber.
